Provided is a filler pipe for fuel, the filler pipe comprising only an inner layer containing a fluorine-containing copolymer having a carbonyl group and a melting point of 250 DEG C or less, an intermediate layer containing a non-fluorine-containing copolymer having an ethylene-based unit and a vinyl alcohol-based unit, and an outer layer containing a polyolefin, the inner layer containing a fluorine-containing copolymer having a carbonyl group and a melting point of 250 DEG C or less, the intermediate layer containing a fluorine-free copolymer having an ethylene-based unit and a vinyl alcohol-based unit, and the outer layer containing a polyolefin. The inner layer, the intermediate layer, and the outer layer are directly laminated in this order, and the outer layer is a layer comprising a polyolefin having a unit based on an acid anhydride, or a layer comprising a polyolefin having a unit based on an acid anhydride, and a layer comprising a polyolefin not having a unit based on an acid anhydride, which are
